Threads from the test period of 11.2a mobile development still available somewhere?

Until the end of february/beginning of march, there was a lot of information available about the test version of Open Edge 11.2a mobile development. Are these threads from the Progress Community still available somewhere?

For example, there was a thread about password validation, but now i get "It appears you're not allowed to view what you requested. You might contact your administrator if you think this is a mistake." when I try to access this link.
